Electric Power (Watt) formulas

\(\large{ Watts = \frac{Volts^2}{Ohms} = P = \frac{V^2}{R} }\)   
\(\large{ Watts = Volts^2 \; Ohms = P = V^2 \; R }\)   
\(\large{ Watts = Volts \; Amps = P = V \; I }\)  
\(\large{ W =  \frac{ m \; g \; h }{ t }    }\) (horsepower)

Where:

\(\large{ P }\) = power

\(\large{ I }\) = current

\(\large{ h }\) = height

\(\large{ m }\) = mass

\(\large{ R }\) = resistance

\(\large{ g }\) = gravitational constant

\(\large{ V }\) = volt
